Hi,

I'm interested in an algorithm (or source code, any language) for calculating the pole locations for an equiripple phase filter. I have sources that provide the pole locations, and software applications that calculate the pole locations, but I need the algorithm. I suspect that it's done by some kind of successive approximation.

Thanks,
K
 

You are correct. There is no closed form solution for equal ripple. It is done on a trial and error method with optimization methods.
